Jahseh Dwayne Onfroy, 20, who went by the stage name pronounced Ex Ex Ex ten-ta-see-yawn, was shot dead on Monday, bringing a violent end to a brief music career that was marked by controversy and arrests.

Authorities said the rapper was ambushed by two suspects. They did not give a motive in announcing Williams’s arrest but previously said the shooting was an apparent robbery attempt.

In just more than 48 hours, #BSO homicide detectives arrested Dedrick Devonshay Williams for the murder of Jahseh Onfroy, also known as XXXTentacion. Williams (dob 3/23/96) was taken into custody shortly before 7p.m. in Pompano. More details will be released later today. pic.twitter.com/OkP2usoqNH

XXXTentacion’s lawyer David Bogenschutz said on Tuesday that investigators told him the rapper had visited a bank shortly before the shooting and possibly withdrew cash to buy a motorcycle at Riva Motorsports in Deerfield Beach.

Williams is charged with first-degree murder without premeditation, a probation violation and not having a valid driver’s licence.

Court records show Williams has been charged previously with several felonies, including grand theft auto, domestic violence, cocaine possession and possession of a firearm by a convicted felon.

XXXTentacion, who sported dreadlocks and facial tattoos, was a rising star. He notched a number one album in March with “?” and had a top 10 hit with “Sad!”.

But he also generated controversy. In 2016, he was arrested on charges including home invasion for a 2015 incident, and less than a month later was jailed on charges that he attacked his girlfriend, who was pregnant at the time. Later, he faced more charges including witness tampering.

In a recent interview with the Miami New Times, XXXTentacion described his upbringing, which included seeing his mother infrequently and being raised by friends, family and baby-sitters. His mother bought him clothes, phones and other gifts. He said he used violence so she would engage with him.
